After 90' s, many countries put more emphasis on the aspects of lightweight, pollution-free and recyclable in the selection of automobile materials.
Comprehensive efficiency provides new opportunities and markets for the expanded application of polypropylene foam in automobiles. To 1996, there are 63.
Species, including GM 19, Chrysler 13 and Ford 8; There are 25 species in Europe, including 3 Mercedes-Benz, 5 Volkswagen and Europe.
6 kinds of treasures; There are 57 species in Japan, Nissan 17, Toyota 15 and Honda 16. At present, some domestic models are also being used.
To foamed PP, such as Shanghai Volkswagen Passat, FAW-Volkswagen Jetta, Bora, Audi, Tianjin FAW Toyota Crown, VIOS,
Le Wei, Li Xia 2000 and Weizi of Tianjin FAW, Chevrolet SUV of GM, Buick GL8, Fukang and Peugeot 307 of Shenlong,
Elysee, Beijing Cherokee, Outlander and other models.
PP foam not only has high heat resistance, high impact energy absorption, good resilience and thermoformability, but also can be recycled.
Make use of the advantages of recycling to manufacture automobile parts, such as steering wheel, top plate, bottom plate, side guard plate, air conditioning steam barrier and so on.
Plate, outer armor plate, door inner plate energy-absorbing protective pad, buffer pad, shockproof plate (pad), headrest, chair backrest, toolbox, instrument.
Car I'-J's box, control box, waterproof layer or sound insulation board, spare tire cover, battery cover, engine cover and back seat of limousine.
Engine compartment. Polypropylene foam is more advantageous than polyethylene foam in areas requiring higher working temperature, such as sun visor and instrument.
The insulation board on the floor and the place where the temperature of two cars I'-If day -l is easy to rise, in addition, it can be used as internal silencing plug-ins and heat insulation materials to reduce vibration.
Core material and damping material.
(1) Automobile interior materials
Automotive interior materials usually adopts a laminate composed of PP (core material), foamed PU (cushioning material) and PVC (outer skin).
Materials. Mitsui Petrochemical Company proposed laminating cross-linked foamed PP with skin materials and cushioning materials to manufacture car sheds and doors.
Interior decoration materials.
